There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?
Reminder that the rules for lemmy.ca still apply!
Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐.

Very good answer. It's really complicated since it's an old protocol and lots of different mechanisms have been added on top. I found one small error: You can't rely on the "received" headers either. Just the line from your mailserver and the IP and hostname right before. The rest of the path (before) can be fake, too. (And this regularly happens.)
